Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468916, here are decompositions:

13 + 31468903 = 31468916
67 + 31468849 = 31468916
139 + 31468777 = 31468916
373 + 31468543 = 31468916
463 + 31468453 = 31468916
547 + 31468369 = 31468916
673 + 31468243 = 31468916
757 + 31468159 = 31468916

Showing the first eight; more decompositions exist.
